important basic concepts with links to resources on the WAI site
(What is Web Accessibility?)

differently-formatted documents (e.g., on-line slides)

Navigation to related documents

Note: One motivation for the Overview pages is that we can't change or add
anything to the Technical Report pages, which are the guidelines, techniques,
and such (under www.w3.org/TR/). For example, we cannot add navigation. The
Overview pages for the guidelines and slides are to meet issues that
usability testing confirmed, including:

users were overwhelmed with the /TR/ documents and uncomfortable with
all the front matter (multiple version links, abstract, status)

users had trouble getting dumped into a /TR/ document without really
knowing where they were going, and thus where they were

once in a /TR/ document, users had trouble getting back to the WAI
sub-site

The audience for the text of the Overview pages are people who are
new to the topic. This includes people who are brand new to
Web accessibility overall, or are familiar with one area of accessibility and
not others (e.g., they know WCAG but not UAAG or ATAG). Therefore, it is
particularly important that the Overview pages:

Use easy-to-understand language and terminology

Are geared toward novices

Are short, preferably less than 2 printed pages

A second primary audience for the Overview pages is
people navigating to the documents. Therefore, it must also
be easy to get to the document links without having to wade through all the
text.
